WebJan 30, 2024 · Aharonov–Bohm effect 1959. The Aharonov–Bohm effect, sometimes called the Ehrenberg–Siday–Aharonov–Bohm effect, is a quantum mechanical phenomenon in which an electrically charged particle is affected by an electromagnetic potential (φ, A), despite being confined to a region in which both the magnetic field B and electric field E … WebApr 9, 2024 · The Aharonov–Bohm effect shows that there are situations in which the phase of the wavefunction of a charged quantum probe is influenced at locations where the magnetic (and electric) field vanishes, whereas the vector potential \(\mathbf{A} \) does not. Thus, in brief, one must conclude that either the magnetic field \(\mathbf{B} \) acts in a …
